$(8$ pts$)$ You are standing at a point $($not necessarily the midpoint$)$ between two speakers playing

the exact same tone of frequency $100$ Hz in phase with each other. At your present position, you

do not hear any sound from the speakers. You know you are $5\mathrm{.}5$ m away from one speaker. How

far could you be away from the other? You can assume the speed of sound is $340$ m$/$s$.$

A$.8\mathrm{.}9$ m

B$.5\mathrm{.}5$ m

C$.12\mathrm{.}3$ m

D$.15\mathrm{.}7$ m

E$.10\mathrm{.}6$ m
